Section 4.8.5 says:

The default value is "last".

It should say:

The default value is “last”, except when used with PUT 
and the target resource already exists, in which case the 
default is to replace the target resource without altering
its position in the "ordered-by user” list or leaf-list.

Notes:

The "last" default is intended for when creating a new element.

A PUT operation that replaces a list or leaf-list entry should not move the entry unless the "insert" parameter is explicitly passed.
